VALMEX vs Hypalon vs Cheap PVC: Which Fabric Survives the Australian Sun?

Choosing an inflatable boat means comparing fabric names and numbers: VALMEX®, Hypalon, PVC, GSM and millimetres. In Australia — with intense UV, high temperatures, salt and abrasive beaches — it pays to understand exactly what you're buying.

Here's a practical comparison of VALMEX®, ORCA Hypalon (CSM) and budget PVC: where each excels, what to watch for, and how to choose for the way you store and use your boat.

What is VALMEX®?

VALMEX® is a range of coated technical fabrics made by the German manufacturer Mehler. For inflatable boats it's a PVC-coated polyester fabric: a woven polyester base provides strength, while PVC coatings make it airtight and protect it from water and wear.

Easy Inflatables uses two grades:

• VALMEX® Heavy Plus — 1500 GSM / 1.2 mm on the Viper Series, rated for a 10–12 year service life. A heavy-duty, commercial-grade fabric used on rescue boats and workboats.
• VALMEX® — 1100 GSM / 0.9 mm on the lighter AeroCat Series, chosen for easy carrying and quick launching.

Both are a very different proposition from thin, unbranded entry-level PVC. You can read the full details and our VALMEX® Heavy Plus technical sheet on the fabrics page.

What is Hypalon, and is it the same as ORCA?

"Hypalon" is the name many boaters use for inflatable fabric with a CSM (chlorosulfonated polyethylene) coating. The original Hypalon-brand material is no longer made, so the name is now used informally. ORCA is a current brand of engineered fabric using CSM and chloroprene rubber coatings over a polyester base.

ORCA is designed for marine use where UV, weather and salt exposure matter. Grades differ in weight and construction, so check the specific grade rather than assuming every "Hypalon" fabric performs the same. Aerowave boats can be ordered with an ORCA Hypalon hull upgrade.

VALMEX® vs Hypalon vs budget PVC: a practical comparison

Treat this as a general guide — exact grades, finishes and construction make a difference.

Which fabric handles Australian sun best?

For maximum UV and weathering resistance, CSM/ORCA has the strongest reputation. That makes it appealing if your boat spends long periods uncovered on a deck, mooring or marina berth, particularly in northern or tropical conditions.

VALMEX® Heavy Plus is an excellent fit for Australia too. It's a quality PVC fabric with documented light fastness and robust mechanical properties, and it shines on boats that are covered or stored out of the sun between trips — which is how most trailer-free inflatable owners use them.

Care makes a big difference with either fabric. A cover, shade, regular rinsing and sensible storage all help, as does following the manufacturer's inflation instructions. An automatic over-pressurisation valve on every chamber manages pressure as the air heats up.

Why cheap, thin PVC struggles

Thin PVC can suit a lightweight tender that's used occasionally and stored carefully. But low-cost PVC with less coating and a lighter base fabric has less material to withstand years of sun, rubbing and frequent handling.

Australian heat and UV accelerate ageing in vulnerable PVC. Over time it can lose flexibility, harden, and develop cracks or surface wear — and aged fabric is harder to repair. That's why a low price or a thickness figure alone shouldn't decide the purchase.

Look at the whole specification: fabric maker and grade, GSM and thickness together, coating, seam construction, warranty and storage advice. "0.9 mm" alone doesn't tell you whether it's branded VALMEX® or an unbranded fabric. Read 0.9 mm vs 1.2 mm: What Hull Fabric Really Buys You and Why a 1.2 mm Hull.

Abrasion, weight and repairs: the trade-offs

Abrasion resistance depends on the fabric grade and boat design as well as how you use the boat. Dragging tubes across concrete, sharp rock or shells can damage any material, so rubbing strips, reinforced areas and launching wheels are worth having if beach launching is part of your routine.

Weight is grade-specific. A heavier fabric adds durability and some weight to the finished boat, so ask about the actual material grade rather than the broad labels "PVC" and "Hypalon".

Repairs need compatible patch materials and adhesives, and correct preparation matters for both. CSM repairs take more specialist knowledge. A small repair is manageable with the right kit; seam damage or a large tear is a job for an experienced repairer. See our repairs and patching guide.

Which should you choose?

Choose ORCA Hypalon if maximum resistance to long-term sun and weather is your priority, especially if the boat will live outdoors, and you're comfortable paying more upfront.

Choose VALMEX® Heavy Plus if you want a substantial, premium fabric with a strong balance of durability and value — particularly if you cover the boat or store it out of the sun. It's a world away from thin, entry-level PVC.

Choose 0.9 mm VALMEX® if light weight and easy carrying matter most — the AeroCat range is built around it.

A well-made boat that's properly cared for will serve you better than a higher-spec fabric left exposed and neglected. Compare the exact fabric grade, seam method, warranty and care requirements, not just the headline material name.
